Abstract

A binaural-recording earphone set is provided. It comprises two speaker units and two microphone units, the two speaker units are inserted into the auditory canal of two ears respectively. The two microphone units are coupled on the two speaker units and can be dismounted. Under a recording mode, the microphone units can be dismounted from the speaker units, and replace the speaker units to be inserted into the auditory canal of the two ears to record external sound. Under a play mode, the speaker units are inserted back into the auditory canal of the two ears to playback the sound recorded previously.

What is claimed is: 
     
         1 . A binaural-recording earphone set comprising:
 two speaker units inserted into the auditory canal of two ears respectively to play sound signals; and   two microphone units detachably coupled on said speaker units;   wherein, when said binaural-recording earphone set is under a recording mode, two of said microphone units are detached from two of said speaker units, and to replace said speaker units to be inserted inside the auditory canal of the pair of ears, two sides of said microphone units for receiving sound face outside the ears.   
     
     
         2 . The binaural-recording earphone set as claimed in  claim 1 , wherein, under said recording mode, two of said microphone units are disposed at the entrances of the auditory canal of the pair of ears. 
     
     
         3 . The binaural-recording earphone set as claimed in  claim 1 , wherein each of said speaker units comprises a body case to accommodate one of said speaker units. 
     
     
         4 . The binaural-recording earphone set as claimed in  claim 3 , wherein a sound tube is extended from a front end of said body case, an earplug is sleeved on said sound induction tube. 
     
     
         5 . The binaural-recording earphone set as claimed in  claim 3 , wherein a cavity is extended from a rear end of said body case for assembling said microphone unit. 
     
     
         6 . The binaural-recording earphone set as claimed in  claim 5 , wherein a fastener is disposed on a circumference of said cavity for fastening said microphone unit. 
     
     
         7 . The binaural-recording earphone set as claimed in  claim 1 , wherein each of said microphone units comprises a body case to accommodate one of said microphone units, and an earplug is sleeved on said body case. 
     
     
         8 . The binaural-recording earphone set as claimed in  claim 7 , wherein said earplug seals the auditory canal. 
     
     
         9 . The binaural-recording earphone set as claimed in  claim 7 , wherein said earplug is disposed on one end of said body case, and a fastening portion is disposed on another end of said body case for fastening said microphone unit with said speaker unit. 
     
     
         10 . The binaural-recording earphone set as claimed in  claim 7 , wherein a fastening portion is disposed on said earplug for fastening said microphone unit with said speaker unit. 
     
     
         11 . The binaural-recording earphone set as claimed in  claim 1 , wherein said microphone unit is magnetically attracted to said speaker unit. 
     
     
         12 . The binaural-recording earphone set as claimed in  claim 1 , wherein, under a noise elimination mode, two of said microphone units are assembled on two of said speaker units, and two of said microphone units receive a surrounding sound source signal, and an opposite surrounding sound source signal is produced for two of said speaker units.
